And again, this is wasting your time.. you should value your own time spent here at something, hopefully more than the cost of a monthly subscription. All the problems you are having are the flakey cloud storage stuff in Pro Tools First. Pro Tools standard (aka “real” Pro Tools) using local sessions have none of this crap to put up with. The thing you, and other users, have control of that will immediately stop all these problems is to stop using First. Otherwise it’s kind of advice that hitting yourself with a hammer in the head hurts... if folks just want to play, sure do whatever. But if this is causing folks frustration just get off this mess. If not Pro Tools Standard, there are lots of great other DAWs (as mentioned).

Does not work also with wired connection. Can I uninstall and reinstall PT to solve the problem? I'm not sure as it is a cloud issue...
I have no projects open.]

Have you tried trashing PTF's Preferences before you erase and re-install PTF? Preferences are located within your user's Library/Preferences/Avid folder. If you don't know how to do it, follow these steps while the PTF app is closed: Click the Finder icon on the dock. On the top menu there will be a "Go" option. Click it once so it shows all its options and then press "alt". You will notice a Library folder shows up while you press "alt." Click that "Library" location. A new Finder window will show up with the Library folder showing its contents. Search for the Preferences folder. Trash the Avid preferences. Start PTF.
If that doesn't work, then it's a server error and you will have to contact via e-mail Avid's support so they reset the account for you.

EDIT: Also, before you do all the steps, sign out of your Avid Link account that shows up in the menu bar.
